Understanding Council Tax Exemptions
A complete breakdown of who qualifies for full Council Tax exemption, the official exemption classes, and the steps to claim your relief.
Exemption vs. Discount: What’s the Difference?
It is crucial to understand the difference between a Council Tax discount and an exemption:
- Discount: Reduces your bill by a percentage (e.g., 25% for a single adult, 50% for two disregarded adults). You still receive a bill and must pay the reduced amount.
- Exemption: Reduces your Council Tax bill to £0. The property is completely free from Council Tax for as long as the qualifying condition applies. No payment is required.
Who Qualifies for Council Tax Exemption?
Exemptions are typically granted based on the status of the residents or the condition of the property itself. Common scenarios include:
- Full-Time Students: Properties where all residents are full-time students are completely exempt.
- Severe Mental Impairment (SMI): Individuals with a certified SMI are disregarded. If they live alone, the property is fully exempt.
- Care Homes and Hospitals: Properties left unoccupied because the owner has moved permanently into a care home or hospital.
- Armed Forces: Properties left unoccupied by members of the armed forces who are required to live in barracks or have moved due to postings.
- Major Repairs: Unoccupied properties that are unfurnished and undergoing major structural repairs to make them habitable.
- Annexes: Self-contained annexes occupied by a dependent relative (e.g., an elderly parent) or used as part of the main dwelling.
Understanding Official Exemption Classes
Local councils use specific letter codes (Classes A to U, and some others) to categorise exemptions. While the exact rules can vary slightly between local authorities, the core classes remain consistent across England, Scotland, and Wales.
For example, Class N applies to unoccupied properties where all residents are full-time students, while Class D applies to properties unoccupied because the owner is in prison (excluding non-payment of Council Tax or fines).
How to Apply for an Exemption
To claim an exemption, follow these steps:
- Identify your class: Determine which exemption category applies to your situation (see the reference table below).
- Gather evidence: Collect the necessary documentation (e.g., a student certificate, a doctor’s letter for SMI, or a care home admission letter).
- Contact your council: Visit your local council’s website and find the “Apply for Council Tax exemption or discount” page. You can usually apply online, by phone, or by post.
- Request backdating: If you were eligible in the past but didn’t claim, explicitly ask the council to backdate your exemption. Provide a valid reason for the delay.

Council Tax Exemption FAQ
Answers to the most frequently asked questions about claiming Council Tax exemptions.
A Council Tax discount reduces your bill by a percentage (e.g., 25% for a single adult), meaning you still pay something. A Council Tax exemption reduces your bill to £0, meaning the property is completely free from Council Tax for as long as the qualifying condition applies.
Yes. Properties occupied entirely by full-time students are completely exempt from Council Tax (Class N). If a student lives with non-students, the student is ‘disregarded’ for Council Tax purposes, which may result in a 25% single-person discount for the household.
Yes, in many cases. If you discover you were eligible for an exemption in the past, you can backdate your claim. Most local councils allow backdating for up to 3 months, but some may allow up to 6 years if you have a valid reason for the delay, such as severe mental impairment or being in the armed forces.
The required proof depends on the exemption class. For students, you need a student certificate from your university. For severe mental impairment, a doctor’s certificate and proof of qualifying benefits are required. For unoccupied properties, evidence of major repairs or the owner’s residence in a care home may be needed.
